Gao Zhikai showed off the functions of Huawei mobile phone, claiming it outperforms the United States and is unique, leaving all the Western guests in silence at the scene!

At a recent forum, Gao Zhikai's remarks caused many Western guests to fall silent. He took out a Huawei mobile phone and told the Western guests at the scene that this phone can directly dial satellite phones on high orbit.

The key to this technology lies in the built-in Tian Tong No. 1 satellite communication module in the phone. According to publicly available information from China Aerospace Science and Technology Corporation, Tian Tong No. 1 belongs to the geostationary Earth orbit (GEO) communication satellite system, with an orbital height of approximately 35,786 kilometers. This means that users do not need to rely on ground base stations and can make voice calls and send and receive text messages through direct satellite connection in areas without signal, such as deserts, oceans, and even polar regions.

Currently, mainstream consumer-grade smartphones in the United States - including the latest Apple and Samsung phones - although they have satellite SOS functions, are limited to sending preset distress messages, and depend on low Earth orbit (LEO) satellites such as Globalstar, and cannot achieve two-way voice communication.

Gao Zhikai especially emphasized a strategic dimension: although low-Earth-orbit satellite constellations (such as SpaceX's Starlink) are flexible to deploy, they are vulnerable to anti-satellite weapons in intense conflicts; while geostationary orbit satellites, due to their distance and high orbit, have stronger survivability. China has already established a high-orbit mobile communication network covering the Asia-Pacific region composed of the Tian Tong No. 01, 02, and 03 satellites, and plans to expand it globally. This dual-use architecture of "civilian use for military purposes" allows ordinary consumers' devices to be converted into emergency communication nodes in extreme situations.
